Verify operations test the integrity of data after a backup. Symantec recommends that you verify all backups. By default, Backup Exec includes a verify operation to run immediately after a backup. You can enable or disable the default verify operation using the Verify after backup option. You can optionally create a verify backup sets template to schedule and run the verify operation independent of the source backup job.
You can use a verify backup sets template to schedule the verify operation to run outside of your backup window. Running the verify operation outside of your backup window may be helpful if your network resources are scarce. If you have difficulty completing backups within the allotted time window, you can schedule the verify operation to run at a more convenient time.
A verify backup sets template is especially beneficial if you use Backup Exec’s Deduplication Option. If you use the default Verify after backup option, Backup Exec must perform the verify operation on both the server-side and the source-side. Backup Exec sends the backup sets across the network to verify them. The process can be time consuming depending on the amount of data you are verifying and your network configuration. If you schedule the operation using a verify backup sets template, the operation runs locally and more efficiently.
